The Alternative Minimum Tax calculator for 2023 is created for quick estimation and comparison of tax liability of certain individuals who are high earners and may be impacted by this lesser-known tax system. Readers should note that because of high exemption limits for applying AMT tax, most taxpayers may not be affected due to this provision.

What is Alternative Minimum Tax?
The AMT provisions were introduced in 1969 in response to public outcry over high-income taxpayers avoiding federal income tax through extensive deductions and credits. Section 55 of the IRC deals with the imposition AMT taxation system.
So, this legislation aimed to tax wealthy persons with substantial income to pay a minimum amount of tax, even if they qualify for significant deductions and credits under the regular tax system.
The AMT system operates parallel to the regular tax system, with its rates, exemptions, and deductions. Taxpayers must compute their tax liability under both systems and pay the higher amounts.

How is the Alternative Minimum Tax Calculated?
Calculating the AMT involves a multi-step process, including:
- Determining your Alternative Minimum Taxable Income (AMTI) by making specific adjustments and preferences to your regular taxable income.
- Subtracting the appropriate AMT exemption amount based on your filing status.
- Applying the relevant AMT tax rates to the remaining AMT income.
- Comparing the calculated AMT tax to your regular tax liability and paying the higher of the two.
What is the AMT tax rates for 2023?
The amt tax rates for 2023 is as under
|Filing status||Tax Rate of 26 %||Tax Rate of 28%|
|Every filing status Except Married Filing separately||Upto MTI of $220,700||Any excess above 220700|
|Married Filing Separately||Upto AMTI of $110,350||Any excess above $110,350|
Alternative Minimum Tax Calculation Example
Let’s consider an example to illustrate the AMT calculation process. John, a single taxpayer, has a regular taxable income of $250,000. He has $60,000 in itemized deductions, including $45,000 in state and local taxes. Let us assume the regular tax liability for 2023 is $52,000. Now we need to find out whether the provision of alternative minimum tax increase the tax liability of Mr John or not.
- Calculate John’s AMTI by adding back the non-deductible state and local taxes to his regular taxable income:$250,000 (regular taxable income) + $45,000 (state and local taxes) = $295,000 (AMTI)
- In 2023, the AMT exemption for a single filer is $73,600. So, taxable income for AMT purposes is determined by subtracting the AMT exemption amount from John’s AMTI. That means $295,000 (AMTI) – $73,600 (exemption) = $221,400.
- The next step is to apply the AMT tax rates for a single filer in 2023, which is 26% on the first $199,900 and 28% on the amount over $199,900.
- So , John’s AMT liability is: (0.26 × $199,900) + (0.28 × ($221,400 – $199,900)) = $51,974 + $6,020 = $57,994
- If this amount of tax under AMT is less than the regular tax liability, there would not be any AMT tax to be paid by John. But if the AMT tax is more than the regular tax, John needs to pay the AMT tax.
- Since John’s regular tax liability is $52,000, since the calculated AMT of $57,994 is higher than his regular tax liability, John must pay the AMT of $57,994.
2023 AMT Exemption and Phaseout Limits
The AMT exemption amounts and phase-out thresholds for 2023 are as follows:

|Married Filing Separately||63400||578150|
These AMT exemption amounts and phase-out thresholds are indexed annually for inflation.
Who Pays Alternative Minimum Tax?
Taxpayers with high incomes who claim significant deductions are the prime target of AMT provision. So, they are, in all likelihood, subjected to the AMT tax. In other words, the chance of AMT tax greatly increases if you:
- Claim substantial itemized deductions, such as state and local taxes or miscellaneous deductions subject to the 2% floor.
- Have significant income from tax-exempt private activity bonds.
- Exercise incentive stock options and hold the acquired stock.
If you suspect you might be subject to the AMT, it’s essential to plan accordingly and consult a tax professional to help you navigate the complexities of the tax system.
What is IRS Form 6521? Who needs to file it?
The computation of AMT is necessary for people who have claimed many deductions.IRS provides form 6251 to help taxpayers to compute and determine if they need to pay Alternative Minimum Tax. If, after filing form 6521, you find you are liable for AMT, you must pay and attach the form 6521 with your tax return.
However, if there is no AMT tax liability as per IRS form 6521, there is no need to attach the form with your tax return. Before completing the amt computation form, read the Form 6521 instructions. I created a Form 6521 Calculator based on the fields given in the form.
What Adjustments are Required for Computing AMT?
When calculating the Alternative Minimum Tax (AMT), you need to determine your Alternative Minimum Taxable Income (AMTI) by making certain adjustments to your regular taxable income. Revenue Ruling 87-89 should be referred for deciding the treatment of some specific Itemized deductions for the alternative minimum tax computation purposes.
These adjustments may increase or decrease your taxable income for AMT purposes. Below is a list of common adjustments in computing AMT:
- If you claimed the standard deduction on your regular tax return, you must add it back to your taxable income when calculating your AMTI.
- You must add back the State and local taxes deducted on Schedule A of Form 1040 to your taxable income when calculating your AMTI.
- If you add back the interest paid on a home mortgage for any loan not used to buy, build, or substantially improve your primary or secondary residence, similarly, interest paid on home equity loans or lines of credit used for purposes other than buy, build, or substantially improve your primary or secondary residence should be added back.
- Medical expenses less than 10% of your adjusted gross income (AGI) should be added.
- Miscellaneous itemized deductions subject to the 2% AGI floor (such as unreimbursed employee expenses, tax preparation fees, and investment expenses) are not deductible for AMT purposes.
- Depreciation can also be added for certain assets. Calculating depreciation for AMT purposes may differ from the method used for regular tax purposes. This can result in different depreciation amounts for the same asset under the two tax systems.
- When you exercise Incentive Stock Options (ISOs) and hold the acquired stock, the difference between the stock’s fair market value and the exercise price is included as a preference item in your AMTI calculation, even though it’s not included in your regular taxable income.
- If you have incurred passive activity loss, limitations may differ for AMT purposes, leading to different passive activity loss amounts being allowed under the two tax systems.
- Tax-exempt interest from certain private activity bonds is considered a tax preference item. It must be included in your AMTI calculation, even though it is not taxable under the regular tax system.
- For AMT purposes, the Net Operating Loss (NOL) deduction is limited to 90% of your AMTI (before the NOL deduction), whereas there is no such limitation for the regular tax system.
These and other less common adjustments are used to calculate your AMTI, which is the starting point for determining your AMT liability.
